PROCESS FOR SEPARATING PRESSURE GAS MIXTURES CONTAINING COMPONENTS SEPARATED AT LOW TEMPERATURE IN A SOLID CONDITION.

摘要

A portion of a pressurized gas mixture containing a component like carbon dioxide which solidifies during cooling is separated into a fraction substantially free of such component and a fraction enriched in such component. The remaining portion of the gas mixture and the two fractions are then fed to different levels of a fractionation zone with the fraction substantially free of such component entering at the highest level and the other fraction at the lowest level.
